I seem to be on a roll lately with people giving me their old film...sadly, no one giving away any Type 55. The latest has Ilford PanF, some FP4 and Kodak Plus-X from at least 25 years ago - it really was stored in a fridge for all or most of that time. Is there any special shooting or developing that has to be done with this? Anything weird in particular happen with film that old? I've also come in to some Fuji 100 slide film with an expiry date of 1980, similarly refridgerated. Can colour shifts or other deterioration over time be taken advantage of to get a particular look or effect?
